Well, in general I would like to keep the rules short and to the point, covering only the most important rules, because if you have a long list of rules I fear that (some) people will not read any of them...

Yes, it would be nice if the rules could be short, clear, & concise, but life isn't clear & concise either. In fact, it would be great if common sense could be the sole rule, but unfortunately, common sense isn't common enough.

Rules typically are put into place to have something to point to later when the same problem crops up again (& again, & again...) hoping that this will squelch any further incessant arguing about how unfair life is, why is the pizza cold, drats, there isn't any beer left, & ouch, this hangnail is bothering me. Just don't do it. It just saves a lot of time & confusion by posting just once.
